Question

Two plane mirrors are separated by 120°, as the drawing illustrates. If a ray strikes mirror M1 at a 1 = 570 angle of incidence, at what angle 2 does it leave mirror M2? The drawing shows a laser beam shining on a plane mirror that is perpendicular to the floor. The beam's angle of incident is 37.6. The beam emerges from the laser at a point that is 1.10 m from the mirror and 1.80 m above the floor. After the reflection, how far from the base of the mirror does the beam strike the floor? Review Conceptual Example 1 as an aid in understanding this problem. The drawings show two arrows, A and B, that are located in front of a plane mirror. A person at point is viewing the image of each arrow. which images can be seen in their entirety? Determine your answers by drawing a ray from the head and foot of each arrow that reflects from the mirror according to the law of reflection and reaches point P. Only if both rays reach point P after reflection can the image of that arrow be seen in its entirety. (Select all that apply.) O image of A o image of B O neither image

Explanation / Answer

By using laws of reflection, left angle of triangle = 90-57 = 33 degree

Top angle of the triangle = 180 - 33- 120 = 27 degree

angle of incidencde on second mirror = 90-27 = 63 degree

Angle of reflection = 63 degree answer
